Help With query

[Tango2310]

Hi,

I am trying to transform a utc date time column to a specific timezone by using DateTime.Add Zone but cant quite get the syantax right.

My code is

= Table.TransformColumnTypes(#"Filtered Rows",{{"utit_quotefinaliseddate", type DateTime.AddZone(["utit_quotefinaliseddate"],10)}}))

Thank in advance for any assistance

DateTime.AddZone does not change the underlying time. It merely adds a TimeZone segment with the stated hours offset.

To change a UTC time to the corresponding time in a specific time zone, you need to add/subtract the number of hours.

If you also want to add a time zone specifier, that is a separate operation.

For example, to change UTC time to Eastern Daylight Time:

Table.TransformColumns(Source, {"Date", each _ + #duration(0,-4,0,0), type datetime}),

To change UTC time to Eastern Daylight Time and also add a timezone identifier:

Table.TransformColumns(Source,{"Date", each DateTime.AddZone(_ + #duration(0,-4,0,0),-4), type datetimezone})

Original UTC Time:

Change to EDT:

Change to EDT and add time zone specifier:

Thanks for your help @ronrsnfld 

Looks like you cant execute this type of query on a Direct Query.

If that is the case, would it be then safe to say that if your using a datasource of Dataverse with any column that has a date, you would need to always use Import during your Transform process?

What is best practice in this type of scenario?

I'm sorry. Those questions are outside my area or expertise.

Pretty sure, you need to be using Table.TransformColumns, not Table.TransformColumnTypes. Also, remove the word "type".
